Here, you can drop off Pokémon you don't want in your party, but that you would like to level up nonetheless. For example, you can leave undesirable Pokémon you want to evolve just to complete your Pokédex, or you could drop off your Magikarp and later on come back to collect a Gyarados. Alas, it's not free. You will be charged 100 for every level your Pokémon gained, but that's a small price to pay for what you get out of it.

The building to the right is the portal to an underground path to Route 6. At the entrance, a woman offers to trade a Nidoran Male for a Nidoran Female (Red & Blue) or a Machoke in exchange for your Cubone (Yellow). You can return later for the trade. The underground path is littered with items that travelers accidentally dropped. There is a Full Restore two squares west of the northern stairs, and a X-Special two squares east and six squares north of the southern stairs.
